Regular Pulley (part of aeroSling XPE and aeroSling ELITE)
Ultra Pulley (standard part of the aeroSling ELITE Plus)
Thanks to the pulleys from mountaineering the aeroSling training is particularly demanding. The standard Pulley of the aeroSling XPE and ELITE is a bit more compact, and provides some more friction, thus control. The Ultra Pulley is a new challenge for advanced users. It is notably more smooth-running, and due to its increased diameter, even more instable and challenging.
